61v on the power tube cathode looks right. 5v there looks wrong. So I suspect the driver transistor in that cathode circuit. Either it is mostly shorted emitter to collector or it is being held on at its base.

There was a brief moment yesterday when I touched pin 8 of V1 that I got some proper signal to the speaker. So then I thought it might be bad connections coming from the tube sockets. I re flowed the board around the sockets and checked continuity.

I suppose it is still possible that these sockets need to be replaced.

If for example the output transformer was faulty. If I Input a sine wave I should still get a proper sine wave on the output valves. Yea?
